Your plaster is irreplaceable.Our holes are small.
In a town of century-old Victorians and center-hall colonials, "exploratory demolition" is a phrase that costs more than the plumbing does. We locate hidden leaks with isolation and instruments first, so the repair is one correct opening rather than a hallway of hopeful patches.

How we find it
The stain is a symptom. The leak is somewhere else
Water travels along joists, down pipes and inside walls before it appears. Opening the ceiling under the stain is how people end up with four holes and a leak still running.
- 01 · Isolate
- Narrow it before you look Shut off zones and fixtures one at a time and watch the meter. This costs nothing and it eliminates most of the house before an instrument comes out of the bag. Supply, waste and heating leaks behave very differently, and this is what separates them.
- 02 · Listen
- Acoustic on pressurised lines A pressurised leak makes a sound with a specific signature, and ground microphones and contact probes pick it up through plaster, tile and slab. This is what puts a location on a wall rather than on a floor plan.
- 03 · Image
- Thermal for temperature difference Wet material holds a different temperature to dry. Thermal imaging maps where water has actually travelled, which is often several feet from where it entered and nowhere near the visible stain.
- 04 · Confirm
- Camera, then one opening Where there's an access route, an inspection camera confirms it before anything is cut. Then one opening, in the right place, sized to the repair rather than to the search.
You get the findings in writing with photographs, whether or not you have us do the repair. If it turns out to be nothing, that's what the report will say — we're not going to invent a leak to justify the visit.
What we see here
What leaks in a Montclair house, and where it shows up
Old houses leak in characteristic places. Knowing the pattern is most of what makes a search quick.
- Original supply runs
- Galvanised and old copper Galvanised corrodes from the inside and pinholes without warning. Old soft copper fails at fittings and where it was strapped too tight. Both leak slowly for months before anything is visible, which is exactly when the water bill starts climbing.
- Second-floor bathrooms
- Tile, pans and waste joints A failed shower pan or a waste joint under a tiled floor produces a ceiling stain below that can be several feet away from the actual failure. Tearing out original tile to find it is the outcome worth avoiding, and it's avoidable.
- Radiator systems
- Heating water, not domestic Houses that still heat with radiators can lose water from valves, unions and returns. A boiler needing constant topping up is a leak somewhere in the loop, and finding it saves the boiler as well as the ceiling.
- Below grade
- Is it plumbing at all? Not every wet basement is a plumbing failure. Groundwater, a failed sump and a leaking supply line look similar and cost very different amounts to fix. Isolation tells you which one you have before anyone starts quoting.
If your water bill jumped with no change in use, or the meter creeps with everything in the house shut off, you have a supply leak somewhere and it's running twenty-four hours a day. That one is worth finding this week rather than next month.
No surprises
What it costs
Detection is priced separately from repair on purpose, so you're not paying for a search inside a repair quote you haven't approved.
Detection is waived when we find and repair the leak in the same visit. Plaster and tile restoration is not included in plumbing pricing and we'll say so plainly at quote stage rather than leaving you to discover it — for original finishes we'd usually recommend your own restoration trade rather than a plumber's patch.

Getting to you
Essex County
Dispatch, parts and the fleet bay all run from 2 John St in Haledon.
Detection is usually scheduled work, but water actively coming through a ceiling is an emergency and gets treated as one — dispatch is live 24 hours with our published 90-minute response or $50 off the job.
Leak detection in Montclair: the questions we get
Can you find it without opening the wall?
That's the entire point of the visit. Isolation, acoustic listening and thermal imaging locate the leak while everything is still closed. There's usually one opening at the end, and it's placed for the repair rather than for the search. Occasionally a leak resists instruments and we'll tell you that honestly rather than cutting speculatively.
How accurate is it, really?
On pressurised supply lines, acoustic detection is generally accurate to within a small area — good enough to open one spot rather than several. Waste leaks are harder because they only run when a fixture runs, so those sometimes need a controlled test. We'll tell you which kind you have and how confident we are before you approve any cutting.
My water bill doubled but I can't see anything.
Classic hidden supply leak. Shut every fixture in the house and watch the meter — if it still creeps, water is going somewhere continuously. That's worth finding quickly, because it's running around the clock and because a supply leak inside a wall eventually finds the plaster.
Will you restore the plaster afterwards?
We make the opening as small as the repair allows and we leave it clean, but we don't restore original plaster or tile — and we'd rather tell you that up front than do a mediocre job of it. For period finishes you want your own restoration trade, and we'll size and place the opening with that conversation in mind.
Is a wet basement always a plumbing leak?
No, and this is worth establishing before anyone spends money. Groundwater, a failed sump and a leaking supply line can look identical on the floor. Isolation and a look at the meter separate them quickly, and if it turns out to be groundwater we'll say so rather than selling you plumbing work that won't help.
Do you provide a report for insurance?
Yes. Written findings with photographs and a description of what was tested and what was found, whether or not we do the repair. Adjusters generally want exactly that, and it's much easier to produce at the time than reconstruct afterwards.
